To all whom t may-concern.-

Ble it known that 1, ALVIN FLAVEL N IMs, a citizen of the" United States, anda resident of Philadelphia, in the vcounty of J eferson and StatptNew York, have invente-d a new and Improved- Concrete-Mixing( Machine, of which the following is a full, clear, and exact description.

yThe purpose of the invention is to provide a s1mple,'durable and economic machine for 4 mixing concrete or other material, and to so construct the machine that it may be used for mixing batches, orfor receiving a continuous feed during operation.

Another purpose of the invention is 'to provide a maclnne'of the character described,.

which will thoroughlymix material in a very short time and one in which the material may be permitted to remain in the machine for any desired length of time, or be released at intervals, or rezleased at 'any time deemed A furtherpurpose of the invention is to provide a concretemixing machine so .constructed that a view may l:be obtained of the interior of the machine at any time, wherebT theprogress ofthe mixing operation can be" observed, and so that li uid may be simultaneously supplied to al vof the. compartments o'r to any particular compartment or groli'p o f compartments, or cut 0H from all.' structiony and combination of the several parts, as vwill be hereinafter fully set forth andpointedfout in the-claims.

Reference is to be ing drawings forming a part of this specification, inv which similar characters of reference Fig. 3 is a parts in the struction;

indicate corresponding parts in all the figures.. side elevation of the improved igure 1 is a machine, parts being broken away; Flg. 2 is a view of the delivery end of the machine; plan view of the machine with the position shown in Fig. 1,' Fig. 4 '1s a side elevation of the iirst or receiving cube of the machine in aposition the reverse of that shown in Fig. 1, a portion ofthe cube being broken away to show its' interior con'- and Fig. 5 is a diagrammatieyiew of two cubes, one in f ull lines and the'other in dotted lines, showing the manner in which they are brought into communication.

The body oiB the machine, which is adapted.

to revolve -as will be hereinafter /set forth, conslsts of any desired number of cubes. In the drawmgs two connected cubes are shown,

e mvention consists in the novel conhad to the accompany- 1 the receiving cube beingdesignated as A and the delivery tube as B; and when a greater number of cubes are employed in the construction of the body the receiving cube is always constructed like the cube A, and the delivery or dispensing cube llike the cube B.

he cubes A and B are both hollow, and the cube A at its outer end at'one corner is provided with an opening 10 into which the material is introduced to be mixed, and at the opposite corner'of the cube in its inner face a about its center wlth an opening 12,usually4 rectangular, and this opening 12 faces the inner end of the cube A, as is illustrated in Figs. 1 and 4. f A side member 13 of the said partition engages with an inner side wall of the cube throughout the length of the said wall, being that side wall through which a portion ofthe opening 11 extends. Another member 13a extends 1n engagement with the inner face of the outer end wall of the saidcube A the full length of the said end wall,

edges to the while a third member-13b is in engagement f with the inner face of the opposite side wall of the cube, but does not extend to the inner end wall of the cube C, thus providing a space `17 between the inner end of the member 13b and the opposingl wall of said cube A. The

member 13 is given more or less of a downward inclination in direction of the inner end of sald cube,

and the outer edge of the member 13 extends parallel with the edge of the opening in the side of the cube and termi nates at whatmay be termed'the bottom wall of said opening 11, as is shown best in Figs. 1 and 4.

The lnner edge of the member 13is provided with a ange 14 extendingup' into the smallerchamberof the cube.

IOC)

A tongue 16, preferably inclined upon its i inner edge, extends down from the inner end of the member 13b of the partition C to 'an engagement with the opposing wall of the. cu

e, thus forming a continuation of the space'orpassage 17 but the'outer lqngitudie end, or the end opposed to the inner end of the cube A, witha rectangular opening 18,

corresponding 1n po'sitiontothe opening 11 v in the. cube A; and when these cubes are brought togetherthey are made to practically interlock at their opposing openings 11 and 18, as is best indicated inDFig. .5, but is shown also in Fig. 1, whereby to establish communication between the cubes. Where the two cubes A and B are brought together they are connected preferably by suitable an le irons 18, as is shown in Figs. 1 and3.

i n o'penin 19 is produced in the corner of the outer en of the delivery cube B, which opening is opposite the opening 18. This opening 19 has a straight base and a straight inner face 19, and an outer opposing inclined wall 19h; and an upper wall 19v that extends unbroken from the wall 19a to the wall 19". The opening 19 being a corner opening extends through only three faces of the cube., but deepest in one face as is shown in Fig. 2.

The member 13 `of the partition C i-n the cube A may be termed a chute member, since it directs material to the? connected openings 11 and 18 in the two cubes; and in the delivery cube B a corresponding chute C is provided, similarly located to the aforesaid chute member 13 of the cube A, and this chute-Cl occupies the same relative position to the cube B as does the chute member 13 to the cube A, the chute C extending" from the inner end wall of the cube B at two-thirds its height to the lower wall of the opening 19 at the delivery end of the said delivery cube B; and at the inner edge of said chute C', which is also 'practically a partition, a iange 21 is provided, extending into the shallower chamber of the cube, since the chute C is so placed that the space between it and one the depth of the cube as in the arrangement wall of the cube will represent one-third of of the partition C in\ the cube A. The fianges 14 and 21 serve to prevent the material sliding from the chutes and also tends to direct said material to the openings at the ends of the chutes.

A door 22 is provided for the rear opening 19, which door is pivoted by a suitable pin 23 to one-side of the cube B, that side in which the triangular wall of the opening 19 is produced. aid door is not intended to entirely cover the opening 19 when the door is closed, as at such time a space is left between the up/per edge of the door and the up'- per wall 191'of'said opening as indicated by' dotted lines in Fig. 2, whereby the person is enabled at all times to look into the machine and note the progress of the mixing operation, as by means of the aligning openings in thecubes almost the entire interior of the cubes Vis rendered visible.

The upward movement of the door 22 is limited by contact with a suitable stop 24 adjacent to its pivot point, and two stops 2` and 26 extend out from the said door, as is also shown in Fig. 2. The upper stop 25 is adapted to be engaged by a spring latch 27, secured to an end face of the said cube B for the purpose of holding the door 22 in an upper position, the lower stop 26 being adapted for 'engagement by the head of a similar latch 28, attached to said face of said cube B for the purpose of holding the door closed.

' The downward movement of the door is limited by engagement with suitable brackets 28a. The head of the latch 27 is provided with a horizontally-extending pin 29, and-the head'of the latch 28 is provided with a corresponding pin 30.

- In mounting the connected cubes A and B, parallel sills 31 are Vlaid on any suitable support, and on each sill uprights 32 are secured, having suitable boxes at their upper ends to journal shafts 33, oney oi which shafts is provided with a gear 34 near its rear end, and `each shaft is provided with two ianged wheels 35, the anges of the wheels on the other shaft 33 being at the opposing faces of the wheels, as is best shown in Fig. 1. The shaft 33 carrying the gear 34 is provided at its rear end with a driving pulley 36, and said' pulley 36 carries a belt 37 connected with any suitable source of power. The two cubesare simultaneously turned at the same rate of speed. i

A ringl guide 38 is secured by means of suitable spokes 38a to the corner portions of each cube A and B, and these I'ing guides are adapted to engage with the guide wheels 35 on the shafts 33, and by reason of the particular location of the iianges on said guide wheels the body of the machine is prevented from movingforward or rearward. Preferably integralwith the guide ring 38 on the cube A an annular ring 39 is formed, provided with exterior teeth whereby the said ring is a skeleton gear,.and the teeth of this gear mesh with the teeth of the gears 34 on the shafts 33, whereby a rotary movement is imparted to the4 body of the machine as the shafts, ,33 are turned. `Uprights 40 are carried up from the sills at the receiving end of the machine, and these uprights support a hopper 41 having a lower contracted lower portion 42 that extends into the opening 1() at the receiving end of the receiving cube A.

' At the delivery end of the machine two tion of the brace for the sta'dard'43a a second trip lever 47 is mounted to turn. If the door v22 is open and it is desired t0 close said door at a certain time in the revolution of the body of the machine, or whenever the door is to beclosed while the machine is in operation, the lever 46 is turned until its inner end is in the path of the pin extension -29 from the upper latch 27, andtherefore when this pin engages with the lever 46 the latch is lifted from the stop `25and the door will fall to closed position by gravity. When it is desired to open the door While the machine is in operation, for the purpose of discharging the contents of the body, the lever47 is brought into position to engage with the projecting pin from the lower latch 28, whereupon -the latch is disconnected lfrom the loweiwpin 26, and as that portion of the body having the outlet opening 19 therein iscarried downward the door opens by gravityand by engagement with the upper latch 27 is held o en until purposely released. `A spout or c ute 48 is secured at the delivery end portion of the machine, usually by attachment to the uprights 43 and 43a; 'and as thematierial flows out from the delivery opening 19 in the delivery cube B the material is received Ass in the said spout 48.

A pipe 49 is'led from any source of water supply. This pipe at its lower end, or end adjacent to the machine` is provided with a bifurcated fitting 50, so that two branch pipes 51 and 52 can he connected with the main 'supply pipe 4), and each branch ipe 51 and 52 is provided `with a control'iing valve-53. Both pipes'l. and 52 are led into the body ol the machine through the receiving opening 10.. The pipe 52, for example,

terminates in the receiving cube A while the pil-P551 is carried through into the delivery cube B. 'The inner end of the pipe 52 is supported ordinarily by a bracket 54 attached to the pipe51, and the innerend ol the pipe 51 is loosely mounted in a bearing'f preferably `secured to the under face of tlie chute C in the delivery cube B as is shown in Figs. 1 and 3. The pipe 52 at its inner end portion is provided Wi th apertures 55a for the escape of Water therefrom, and the inner end of the i pipe 51 located in the delivriry cube B is provided with suitable apertures 56 for a similar purpose. Thus it will be observed that water, or `any desired liquid. can he supplied individually to'either of the cubes, or can he supplied to all of the cubes; andif a number of cubes areemployed to form the body poi'- with an inlet opening angl tion of the machine, water or liquid could be supplied to any particular gioup of cubes.

' In the operation oi the machine, as the cube sections are revolved the entering material will drop to the lowest point in thereceiving cube section A, sliding from corner t'o corner, and will continue thus to change its osition in the lar e chamber of said receiving cube section and in traveling along the under face of the partition or shelf C in said receiving cube section A said material the cliutemember l13 of the partition C, by

which it is conducted to the registering openings 11 and 18, Where 1t is again tumbled' from corner to corner in the delivering or dispensing cube section B, untiliinally landing upon the ehutelC it passes out through the exit opening 19 in the delivery or dispensingv cube section B, rovided said opening is uncovered, and nring the entire rocess, whether the door 22'is open or close the attendant Will have a full view of the interior of the cube'sections. i

The tongue 16, extending down from-the partition C in the receiving cube section A, is particularly designed to deiiect the material from a straight passage tothe communicating openings 11 and 18, provided the 1nate` rial enters the receiving cube section A when in alposition intermediate of its proper re eeiving' ordelivery positions, since atsuch time the material will strike tlie said tongue 16' and will be forced toundergo the saine circuit or procedure as if the material were entered at the most favorable position of the said cube section. i

Having thus described my invention, I claim as new, and desire toI secure by Letters Patent,-
